Deuteronomy 33:18

And of Zebulun he said, Rejoice, Zebulun, in thy going out; and, Issachar, in thy tents.

And of Zebulun he said,.... The tribe of Zebulun, as the Targums of Jonathan and Jerusalem, with whom Issachar is joined, they being brethren, and of the same mother as well as father; though Zebulun the youngest is set before Issachar the older, as in Jacob's blessing, Genesis 49:13;

Rejoice, Zebulun, in thy going out; in their going out to sea, to merchandise, to traffic in foreign parts, it being a maritime tribe, see Genesis 49:13; and so are called upon to rejoice and be thankful for their safe preservation on the seas, and success in trade; and to this sense are the paraphrases of Jonathan and Jerusalem: though Onkelos interprets it of their going out to war against their enemies, and certain it is that they were also a warlike as well as a seafaring tribe; see Judges 5:18;

and Issachar, in thy tents; being a tribe that stayed at home, and attended to husbandry, and dwelt in tents, to take care of and feed their cattle; in doing which they should be prosperous, and have occasion to rejoice, and be thankful to the Lord: though the Targums of Jonathan and Jerusalem carry it to a different sense, to their schools, in which they dwelt: this tribe being, as supposed, a learned tribe, studious, in the law; which is gathered from 1 Chronicles 12:32.
